Abstract :Canopy temperature measurements with infrared thermometry have been extensively studied as a means of assessing plant water status for field and row crops. Achieving high quality peach fruit depends on the ability to maintain mild to moderate levels of water stress in the crop during the growing season. The paper examined the spatial distribution of tree canopy temperature insert ignore into journalissuearticles values(Tc); using thermal images in a peach orchard for irrigation scheduling. The variation of Tc was investigated in three irrigation regime treatments insert ignore into journalissuearticles values(factor A); that produced various soil moisture content insert ignore into journalissuearticles values(SMC); values, three cardinal points insert ignore into journalissuearticles values(factor B);: South, North and East-West aspects combined, and five up-down vertical position measurements insert ignore into journalissuearticles values(factor C: upper, middle upper, middle, middle lower and lower); across the tree canopy thermal images. It was found that Tc was significantly influenced by the irrigation regime. Cardinal point showed a significant Tc difference between South on the one hand and the other aspects. The vertical position within canopy image did not significantly influence Tc.
